WARNING
•
Do not use the product in explosive or corrosive environments, in the
presence of flammable gases, in places subjected to splashing water, or near
combustibles. Doing so may result in fire, electric shock or injury.
•
Do not transport, install the product, perform connections or inspections
when the power is on. Always turn the power off before carrying out these
operations. Failure to do so may result in electric shock or equipment damage.
•
Do not use a motor in a vertical application. If the driver’s protection function is
activated, the motor will stop and the moving part of the equipment will drop,
thereby causing injury or equipment damage.
•
Do not machine or modify the motor cable or connection cable. Doing so may
result in fire, electric shock or damage to equipment.
•
Do not forcibly bend, pull or pinch the cables. Doing so may result in fire,
electric shock or damage to equipment.
•
Do not touch the motor or driver when conducting insulation resistance
measurement or dielectric strength test. Accidental contact may result in
electric shock.
•
Do not disassemble or modify the motor (gearhead). Doing so may result in
electric shock, injury or equipment damage. Should you require inspection or
repair of internal parts, please contact the Oriental Motor branch or sales office
from which you purchased the product.
•
Only qualified and educated personnel should be allowed to perform
installation, connection, operation and inspection/troubleshooting of the
product. Handling by unqualified and uneducated personnel may result in fire,
electric shock, injury or equipment damage.
•
The motor and driver are Class
I
equipment. When installing the motor and
driver, connect their Protective Earth Terminals. Failure to do so may result in
electric shock.
•
Use a motor (gearhead) and driver only in the specified combination. An
incorrect combination may cause in fire, electric shock or equipment damage.
•
Always turn off the power before performing maintenance/inspection. Failure
to do so may result in electric shock.

CAUTION
•
Do not use the motor (gearhead) beyond the specifications. Doing so may
result in fire, electric shock, injury or damage to equipment.
•
Do not touch the motor (gearhead) while operating or immediately after
stopping. The surface of the motor (gearhead) is hot and it may cause a skin
burn(s).
•
Do not leave anything around the motor and driver that would obstruct
ventilation. Doing so may result in damage to equipment.
•
Do not carry the product by holding the motor (gearhead) output shaft or any of the
cables. Doing so may result in injury.
•
Do not touch the motor output shaft (tip or pinion) with bare hands. Doing so
may result in injury.
•
When assembling the motor (pinion shaft) with the gearhead, exercise caution
not to pinch your fingers or other parts of your body between the motor and
gearhead. Injury may result.
•
When installing the motor (gearhead) in the equipment, exercise caution not
to pinch your fingers or other parts of your body between the equipment and
motor or gearhead. Injury may result.
•
Do not touch the rotating part (output shaft) when operating the motor. Doing
so may result in injury.
•
Securely install the motor (gearhead) to their respective mounting plates.
Inappropriate installation may cause the motor (gearhead) to detach and fall,
resulting in injury or equipment damage.
•
Provide a cover on the rotating part (output shaft) of the motor (gearhead).
Failure to do so may result in injury.
•
Securely install the load on the motor (gearhead) output shaft. Inappropriate
installation may result in injury.
•
Be sure to ground the motor and driver to prevent them from being damaged by
static electricity. Failure to do so may result in fire or damage to equipment.
•
The motor surface temperature may exceed 70 °C (158 °F)
even under normal operating conditions. If the operator is
allowed to approach a running motor, attach a warning label
as shown in the figure in a conspicuous position. Failure to do
so may result in skin burn(s).
Warning label
•
Dispose the product correctly in accordance with laws and regulations, or
instructions of local governments.
Precautions for use
Be sure to match the motor output power with the driver output power.
z
Connecting the motor and driver
Use an accessory connection cable (sold separately) when extending the wiring
distance between the motor and the driver.
z
Grease measures
On rare occasions, grease may ooze out from the gearhead. If there is concern over
possible environmental damage resulting from the leakage of grease, check for
grease stains during regular inspections. Alternatively, install an oil pan or other
device to prevent leakage from causing further damage. Oil leakage may lead to
problems in the customer’s equipment or products.
z
Caution when using under low temperature environment
When an ambient temperature is low, since the load torque may increase by the oil
seal or viscosity increment of grease used in the gearhead, the output torque may
decrease or an overload alarm may generate. However, as time passes, the oil seal or
grease is warmed up, and the motor can be driven without generating an overload
alarm.
z
Do not conduct the insulation resistance measurement or dielectric
strength test with the motor and driver connected
Conducting the insulation resistance measurement or dielectric strength test with
the motor and driver connected may result in damage to the product.
z
Rotation direction of gearhead output shaft
In the case of the combination type-parallel shaft gearhead, the rotation direction of
the gearhead output shaft may differ from that of the motor output shaft depending
on the gear ratio of the gearhead.
